Responsibilities for chemical safety

All staff including postgraduate research students will be expected to attend the appropriate chemical safety training courses (details are given in the Graduate School Resource File) and will have access to safety information on the University Health and Safety web page. All undergraduate and taught MSc students must attend a course on Safety and Laboratory practice (details provided in intoductory packs and included in timetables).

Laboratories are designated work areas and are not to be adapted into living space or recreation areas.

All work should be to the standard of Good Chemical Practice (GChP). GChP sets the minimum standard for ensuring the protection of people against the adverse effects of chemical substances encountered at work. Details of GChP can be found on UHSP/15/HS/03. The main points of GChP are as follows:

1.Food, drink, cosmetics and cigarettes must not be taken into or used in the laboratory. Pipetting by mouth is prohibited.

Laboratories and communal areas are designated as NO SMOKING.

  1. Benches should be cleaned and tidied regularly, surplus apparatus and chemicals returned to the stores or cupboards.
  2. Laboratory coats must be worn when working in the laboratory.

4.Laboratory coats should be removed on leaving the laboratory area and MUST NOT be worn in coffee rooms, common rooms etc.

5As a minimum, Safety spectacles or face visors must be worn to protect the eyes from splashes when handling hazardous liquids. When the risk from splashing is high, especially from toxic or corrosive liquids, a visor or goggles must be worn.

6.Work must be carried out cleanly with the minimum of spilling and splashing to minimize contamination. Contaminated areas should be cleaned as soon as possible. The work area must be kept tidy and chemicals returned to the approved storage areas when not in use.

7.Where it is necessary to avoid the inhalation of fumes and vapours or the build up of an explosive atmosphere (from highly flammable liquids or gases) a fume cupboard must be used. Fume cupboards should not be used for storage of chemicals.

8.Flammable substances must be kept well away from sources of ignition - naked flames, hot plates etc.

9.Minimise exposure to fumes and vapours by covering vessels and by prompt replacement of caps and stoppers to bottles when handling volatile or dusty chemicals.

  1. Winchester bottles and liquid nitrogen must be carried in the special carriers.
  2. Hands must be washed before leaving the laboratory area.
  3. Highly toxic chemicals must be stored in a locked container and a record of this store maintained.
  4. All work with carcinogens must be in accord with the guidelines provided at UHSP/15/HS/03 Schedule 3.3.
  5. Containers must be adequately labelled to identify contents and to identify risk phrases.

There are nine specific hazards associated with chemicals, each having its own warning symbol on a bright orange background. These symbols are given on bottles and in catalogues.

The following protective equipment etc. are available from Stores :

Laboratory coats

Gloves, of various types, and barrier creams

Goggles and spectacles

Dust masks

Winchester carriers

All accidents involving chemicals must be reported immediately to the Deputy School Manager (Tel. 46551).

Supervisors have a responsibility for assessing the risk to health and safety from any chemical hazard and for ensuring that working procedures are assessed and designed to minimise risk. They are responsible for ensuring that all activities involving chemicals or that may release chemicals have been assessed as required by University Hazardous Substances Policy.

The Law and University Hazardous Substances Policy

The Health and Safety at Work Etc Act 1974 and regulations made under it such as the Management of Health and Safety at Work Regulations and theControl of Substances Hazardous to Health (COSHH) Regulations impose legal requirements on work involving hazardous substances.

The law requires:

Assessment of the hazard (potential to cause harm) and risk (likelihood of harm under conditions of use) to the health and safety of people at work (and visitors) of the substances with which they are working.

  1. Prevention or adequate control of exposure to or risks from such substances.
  1. Adequate maintenance of plant and personal protective equipment needed for prevention or control.
  1. Monitoring exposure at the workplace if prevention cannot be achieved.
  1. Health surveillance where necessary.
  1. The provision of information, instruction and training for staff.

The over-riding requirement of the law is that work involving hazardous substances is prohibited unless a suitable and sufficient risk assessment has been made and the controls and other findings of the assessment put in place.

University Health and Safety Policy, including Hazardous Substances Policy, is based on the legal requirements. Compliance with University Policy should ensure compliance with the law.

Forms for Chemical Hazard and Risk assessments and associated guidelines are available from the School Safety Office (Room SG23 tel.46557; ) and from the School server ( Advice can also be obtained from the School Safety Office. All assessments will be given an accession number. The accession numbers should be noted on all order forms for chemical purchase. A database of School assessments has been initiated and can be accessed via All assessments will be kept by the Safety Office and should also be available as a hard copy in the relevant laboratory.

HAZARDOUS WASTE DISPOSAL

Procedures for the disposal of hazardous wastes

  1. carcinogens
  2. phenol
  3. mercury
  4. ethidium bromide
  5. cyanogen bromide
  6. acrylamide

are all given on

WASTE SOLVENTS

At the point of production, waste solvents must be collected in securely closed screw-capped 2 litre Winchester bottles (partially filled) in two categories:

Halogenated (ie. Those that contain chlorine, bromine, fluorine or iodine)

Non-Halogenated (not containing halogens in any form)

These should be labelled (remove or cover the original label) with a waste solvent label available from Stores. Waste solvents should be taken to Stores.

TRANSPORT OF LIQUID NITROGEN

All transport of liquid nitrogen should be with the use of special containers (dewars) designed for this purpose. A barrier system must be used when transporting by lift to ensure that no personnel travel with it. The barrier system is available from the Stores and should be positioned inside the lift doors with the dewar during transport. The barrier includes a sign indicating DANGER/DO NOT ENTER.

Glossary of Laboratory Safety

ACID storage - stand bench bottles in a tray. Keep Winchesters in trays to contain breakages within the bin.

ACID PERCHLORIC - stand bench bottle in a full - size beaker.

CARCINOGENS- All work with carcinogens must be in accord with University Guidelines provided at UHSP/15/HS/03 Schedule 3.3 (Replaces USP/80/CR/2) . The Health and Safety Unit must be informed.
